A tracking parabolic concentrator was built from easily available and affordable components. Simplicity and ease of assembly were prime considerations. Considerable experience was gained in the design, assembly and testing. The system performed reasonably well considering its simplicity and...

Endoreversible thermodynamics are used for studying the influence of a planet's thermal conductance on conversion of solar energy into wind energy. Results indicate a strong dependence of the rate of wind energy generated on the amount of heat leaking by conduction form the illuminated side to...

During the winter months in regions where constant electric power supply cannot be relied upon, power may be derived parasitically from heating stoves. A proportion of heat from these 20–50 kW wood or diesel-heated stoves may be utilized to drive a thermoelectric generator (TEG) consisting of...
